src/device/oprom: Fix bootsplash display code for optionroms

So far the bootsplash is only correctly rendered if the framebuffer is
set up as 1024x768@16.
Different resolutions did not show anything, differnent depth resulted
in the distorted images.

This commit removes this limit by using the actual framebuffer resolutions and combines
the code for x86 and yabel.

For the moment the bootsplash is still limited to VGA-OptionROM framebuffer init.

It was tested in 1280x1024@32 on the wip razer blade stealth using the intel vgabios.
